The new property tax rules, translated for your portfolio.
A two-minute calculator that shows what indexation, the 30% minimum tax, and the negative-gearing changes mean for the property you own — or the one you’re thinking about buying.
Three changes reshape the maths for almost every Australian property investor.
Capital gains on investment property face a 30% floor — even if your marginal rate is lower.
The CGT discount no longer applies to established residential property bought after the cut-off.
Grandfathered properties get one calculation up to the cut-off, and the new rules from then on.
Old rules. New rules. The difference in plain English.
Enter your property details and we’ll show both calculations side-by-side, with a one-line explanation of what changed and a clear net delta at the bottom.
- Indexed cost base with your CPI assumption
- Effective rate, including where the 30% minimum binds
- Split calculations for properties bought before 1 July 2027
- Compare up to four scenarios side-by-side
